According to reports, French energy group EDF plans to test four tidal generator sets with a total capacity of 2MW installed near Brea on the 31st.
According to the EDF, the total investment of the project is nearly 40 million euros, and the company will receive subsidies provided by the EU and French environmental and energy agency Ademe.
The company OpenHydro is responsible for designing the turbine units, while the French shipbuilding company DCNS is responsible for assembling the equipment.
A wheel generator is a new generator set that takes power from the ocean current. The energy generated by the tidal turbine will be converted through a set of rectifiers and transported to the mainland via underwater cables.
The project will be prepared to be implemented. Local authorities will fully support this research and development and implementation.
Tide power generation is to build a water barrier dam in a bay or tidal estuary to form a reservoir, and place a water turbine generator set in or next to the dam, using the rise and fall of the seawater level during the tide to make the seawater push the water turbine generator set to generate electricity when the seawater passes through the turbine. From an energy perspective, it is to use the potential and kinetic energy of seawater to convert it into electrical energy through a hydrowheel generator.
The first is a single-store one-way power station. That is, only one reservoir is used to generate electricity only at high tide (or low tide). This is the type of Shashan Tide Power Station in Wenling County, Zhejiang Province, my country.
The second type is a single-store bidirectional power station. Use a reservoir, but power can be generated at high and low tides, but power cannot be generated at low tides. This is the type of Zhenkou Tide Power Station in Dongguan County, Guangdong Province and Jiangxia Tide Power Station in Wenling County, Zhejiang Province.
The third type is a two-store bidirectional power station. It uses two adjacent reservoirs to make one reservoir enter water at high tide and another reservoir release water at low tide. In this way, the water level of the previous reservoir is always higher than that of the latter reservoir, so the former is called the upper reservoir and the latter is called the lower reservoir. The water turbine generator set is placed in the partition dam between the two reservoirs. The two reservoirs always maintain a difference in water level, so power generation can be generated throughout the day.
